Cheshire Phoenix beat Glasgow Rocks 80-61 on Sunday to register a sixth successive BBL Championship win and force their way into the title race.
Phoenix lost four of their first six games but, under the guidance of former NBA Development League coach John Coffino, are now up to joint-third.
Demond Watt's 23 points and 13 rebounds achieved the win that took Cheshire four points behind leaders Newcastle.
"It's all down to our defensive effort," said forward David Aliu.
"Offensively we are very talented but defence is what is getting us through. We owe it all to the coach, who has drilled that into us since day one.
"We have a solid group now and have started clicking so I'm excited for the rest of the season."
